Forecast news: Moderate snow for the northern mountains, red flag warning southwest #COdrought #COwx

From the National Weather Service Grand Junction office:

A low pressure system and associated cold front will slowly sag southward across the region today through Tuesday morning. This storm system will bring periods of showers and isolated thunderstorms to the northern Colorado mountains/valleys, with a minimal chance of showers elsewhere. Moderate snow amounts are expected for the northern CO mountains with winter weather advisories in effect. Across far southwest Colorado, a Red Flag Warning is in effect this afternoon/evening due to expected low relative humidity, gusty winds and dry fuels. It will be much cooler on Tuesday behind the cold front, with showers diminishing in the afternoon. A gradual warm up begins Wednesday with above seasonal temperatures by Friday, it will also generally be dry the latter part of the week aside from a few mountain showers.

From the National Weather Service Pueblo office:

A new weather system is expected to enter the Rocky Mountain region Monday…pushing a surface cold front southward through Colorado by evening. Timing of the front should allow temperatures to warm to Sunday’s readings or higher…before cooler air starts to spill through the area late in the day. Rain and snow showers are possible most of the day over the mountains…while the region’s lower elevations will likely see precipitation delayed until the frontal passage in the afternoon and evening.

From the CoCoRaHS blog:

Deep snow cover over Canada has maintained the supply of cold air this spring and there is still 30 cm (12 inches) or more on the ground across the Prairie provinces. A persistent upper level trough pattern over over the central U.S. has deflected the storm track farther south this spring and allowed the cold air to spill farther south than normal.

In the past two days more than 600 record lows and 560 record low maximum temperatures have been recorded from the Dakotas to the southern tip of Texas…

Is there light at the end of the tunnel? There’s a light, but it might be another freight train, at least in the short term. An upper level system is moving into the Pacific Northwest today and will drop into the central Rockies by Tuesday. The surface low will organize in the Central Plains and bring another round of snow to an area from Wyoming and Colorado to Minnesota. Another surge of cold air will follow this system.

From the National Weather Service Pueblo office:

A cold front will move through the eastern plains of Colorado this evening and bring much colder air to the region. Expect any rain showers to quickly change to snow. Blowing snow can be expected as winds will be very gusty behind the front. Temperatures, after being near 70 degrees in many areas, will fall to the low to mid 20’s tonight.

From the Fort Collins Coloradoan:

The National Weather Service is calling for rain early in the day Monday followed by snow showers after noon. Daytime accumulation is expected to be minimal as winds gust up to 25 miles per hour. Weather service forecasters predict a 70 percent chance of precipitation. Overnight Monday, the snow is expected to continue with calmer winds and a forecast low of 20 degrees. The weather service predicts one to three inches of snow overnight. The chance of precipitation is forecast at 80 percent.
